"Use dual convection for virtually any baking, roasting, or broiling you do. You’ll see (and taste) levels of consistency and guesswork-free precision you never knew were possible. That’s because of an innovative technology, exclusive to Wolf, that uses two fans and multiple heating elements to control heat and airflow more precisely and produce more uniform temperature without the hot and cool spots common with less sophisticated single convection systems. Bake three racks of cookies without even having to rotate the trays." Sub-Zero & Wolf
